I connect an ATX power supply to a motherboard, it works fine.
Connecting another two ATX power supplies (taken from working computers) to same motherboard does not power the board.
For connection I used only one 20 pin (P1 http://www.support.dell.com/support/edocs/systems/dmag/techovu.htm) connector.
Is it possible that some power supplies need something more to make them work, say jumpers on motherboard?
One of "non-working" power supplies is from Dell Dimension.
Thanks.
